BACKGROUND:Multiple sclerosis is a chronic inflammatory demyelinating disease of the central nervous system mediated by T cells.The Toll-like receptors(TLRs)/myeloid differentiation factor 88(MyD88)/nuclear factor kappa-B(NF-κB)signaling pathway plays an important role in the development of the disease.Exploring the specific mechanism of the signaling pathway is essential for further treatment of the disease and improving the prognosis of patients. OBJECTIVE:To review the TLRs/MyD88/NF-κB signaling pathway and its role in multiple sclerosis/experimental autoimmune encephalomyelitis models,which provides new ideas and strategies for the treatment of multiple sclerosis by inhibiting the TLRs/MyD88/NF-κB signaling pathway. METHODS:The literature related to the topic from January 2002 to December 2022 was searched in CNKI,WanFang and PubMed databases.A total of 61 articles were finally included for analysis. RESULTS AND CONCLUSION:The TLRs/MyD88/NF-κB signaling pathway is an important pathway that triggers a pro-inflammatory immune response.The TLRs/MyD88/NF-κB signaling pathway plays an important role in the development of multiple sclerosis by regulating the antigen presentation of dendritic cells,destroying the integrity of the blood-brain barrier,and promoting the activation of T cells,B cells and microglia.By targeting TLRs,MyD88 and NF-κB molecules,inhibiting the activation or signal transduction of TLRs,MyD88 and NF-κB,and reducing the secretion of pro-inflammatory factors,multiple sclerosis can be treated.Animal studies have shown that active ingredients of traditional Chinese medicines,such as flavonoids and glycosides,and traditional Chinese medicine compound formulas,such as Buyang Huanwu Tang,can also treat experimental autoimmune encephalomyelitis by regulating the TLRs/MyD88/NF-κB signaling pathway,which points to the direction of searching for medicines targeting the TLRs/MyD88/NF-κB signaling pathway for the treatment of multiple sclerosis.

ObjectiveTo comprehensively analyze the impact of health literacy on fourth-grade students in a primary school in Changning District through the implementation of interactive interventions， providing a theoretical basis for the effective implementation of school health literacy initiatives. MethodsUsing a cluster random sampling method， the effects of a 6-month interactive intervention were assessed among all fourth-grade students through two rounds of health literacy questionnaires conducted before and after the intervention. ResultsFollowing the intervention， there was a significant increase in the overall rate of health literacy （86.80%）， knowledge of health beliefs （71.57%）， adherence to a healthy lifestyle （92.89%）， and basic health skills （76.14%） （P<0.001）. The rate of formation of student health behaviors after the intervention （90.10%） increased by 16.02% compared to the pre-intervention level （P<0.05）. ConclusionConducting interactive interventions can stimulate students’ enthusiasm for self-directed learning， facilitate the formation of health behaviors， and reduce the risk of disease occurrence. This approach plays a positive role in promoting students’ physical and mental health development and enhancing their level of health literacy.

Objective To analyze the current status,hotspots,and trends in the research field of traditional Chinese medicine and pharmacy combined with transcatheter arterial chemoembolization(TACE)for the treatment of hepatocellular carcinoma.Methods The relevant literatures on traditional Chinese medicine and pharmacy combined with TACE treatment for hepatocellular carcinoma collected by China National Knowledge Infrastructure from January 1994 to December 2022,and use CiteSpace 6.1.R6 software to analyze its publication volume,authors,research institutions,and key words.Results This study included a total of 686 articles.The publication volume showed a fluctuating upward trend from 1994 to 2015,but it had decreased since 2016,indicating that further breakthrough research was needed in this field.The communication between authors and research institutions needed to be strengthened,with low levels of cross institutional and cross regional cooperation and uneven geographical distribution.Cooperation should be strengthened.High frequency key words included hepatocellular carcinoma,Chinese materia medica,interventional therapy,therapeutic,etc.,resulting in 9 key word clustering labels.Conclusion Currently,there is a lack of experimental research and related mechanism research,the future research hotspots of traditional Chinese medicine and pharmacy combined with TACE treatment for hepatocellular carcinoma will focus more on traditional Chinese medicine and pharmacy,interventional therapy,clinical observation,and cell apoptosis,which provides new ideas for researchers conducting related research in the future.

Objective:To evaluate the effectiveness and safety of concurrent chemoradiotherapy combined with nimotuzumab in the treatment of patients with inoperable esophageal squamous cell carcinoma (ESCC).Methods:A retrospective analysis was conducted on the clinical data of 503 patients with inoperable ESCC who underwent concurrent chemoradiotherapy in the Department of Radiation Oncology, Changzhou No. 2 People′s Hospital Affiliated to Nanjing Medical University and Department of Radiation Oncology, Affiliated Hospital of Jiangnan University from 2014 to 2020. Among these patients, 69 received concurrent chemoradiotherapy combined with nimotuzumab (the combined therapy group) and 434 received concurrent chemoradiotherapy alone (the concurrent chemoradiotherapy group). Patients of both groups were matched at a ratio of 1∶2 using the propensity score matching (PSM) method. As a result, 168 patients were determined for clinical analysis, including 61 in the combined therapy group and 107 in the concurrent chemoradiotherapy group. The short-term efficacy and adverse reactions of both groups were compared. The overall survival (OS) curves and progression-free survival (PFS) curves were plotted using the Kaplan-Meier method for the Log-rank test.Results:The two groups showed no statistical difference ( P > 0.05) in clinical baseline characteristics after the PSM. The objective response rate (ORR) of the combined therapy group was significantly higher than that of the concurrent chemoradiotherapy group with statistically significant differences (85.2% vs. 71.0%, χ2 = 4.33, P = 0.037). There was no statistical difference (98.4% vs. 91.6%, P > 0.05) in the disease control rate (DCR) between the two groups. The combined therapy group had median PFS of 28.07 months and 1-, 3-, and 5-year PFS ratios of 78.2%, 37.5% and 29.1%, respectively. The concurrent chemoradiotherapy group had mPFS of 19.54 months and 1-, 3-, and 5-year PFS ratios of 72.9%, 28.3% and 21.3%, respectively. Both groups showed statistically significant differences in PFS ( χ2 = 4.49, P = 0.034). The combined group had median OS of 34.93 months and 1-, 3-, and 5-year OS ratios of 88.5%, 46.8% and 37.4%, respectively. The concurrent chemoradiotherapy group had mOS of 24.30 months and 1-, 3-, and 5-year OS ratios of 81.3%, 35.2% and 28.0%, respectively. Both groups showed statistically significant differences in OS (χ 2= 5.11, P = 0.024), but did not show statistical differences ( P > 0.05) in the severity degree of each adverse effect during the treatment. Conclusions:Concurrent chemoradiotherapy combined with nimotuzumab can improve the ORR and prolong the PFS and OS of patients with inoperable ESCC compared with concurrent chemoradiotherapy alone. Furthermore, combining with nimotuzumab does not increase adverse effects and can be tolerated by patients with high safety.

Tbx18,Wt1,and Tcf21 have been identified as epicardial markers during the early embryonic stage.However,the gene markers of mature epicardial cells remain unclear.Single-cell transcriptomic analysis was performed with the Seurat,Monocle,and CellphoneDB packages in R software with standard pro-cedures.Spatial transcriptomics was performed on chilled Visium Tissue Optimization Slides(10x Genomics)and Visium Spatial Gene Expression Slides(10x Genomics).Spatial transcriptomics analysis was performed with Space Ranger software and R software.Immunofluorescence,whole-mount RNA in situ hybridization and X-gal staining were performed to validate the analysis results.Spatial transcriptomics analysis revealed distinct transcriptional profiles and functions between epicardial tissue and non-epicardial tissue.Several gene markers specific to postnatal epicardial tissue were identified,including Msln,C3,Efemp1,and Upk3b.Single-cell transcriptomic analysis revealed that cardiac cells from wildtype mouse hearts(from embryonic day 9.5 to postnatal day 9)could be categorized into six major cell types,which included epicardial cells.Throughout epicardial development,Wt1,Tbx18,and Upk3b were consistently expressed,whereas genes including Msln,C3,and Efemp1 exhibited increased expression during the mature stages of development.Pseudotime analysis further revealed two epicardial cell fates during maturation.Moreover,Upk3b,Msln,Efemp1,and C3 positive epicardial cells were enriched in extracellular matrix signaling.Our results suggested Upk3b,Efemp1,Msln,C3,and other genes were mature epicardium markers.Extracellular matrix signaling was found to play a critical role in the mature epicardium,thus suggesting potential therapeutic targets for heart regeneration in future clinical practice.

AIM: To observe the effects of single-dose of fentanyl on sedation and agitation during recovery after pediatric adenotonsillectomy day surgery during anesthesia induction. METHODS: A total of 157 children undergoing elective adenotonsillectomy, with ASA physical status I or II, aged 3-10 years were selected during January and March in 2022 in the Second Affiliated Hospital of Wenzhou Medical University. The children were divided into two groups according to random number table method: remifentanil combined with fentanyl group (group RF, n = 78) and remifentanil group (group R, n = 79). Children in group RF received a single-dose injection of 1 μg/kg of fentanyl and 2.5 μg/kg of remifentanil during induction, children in group R received an equal volume of normal saline and 2.5 μg/kg of remifentanil injection. Children in both groups were intubated after propofol induction and anesthetized with combination of sevoflurane-remifentanil. The incidence and severity of emergence agitation (EA), Ramsay sedation score and FLACC pain score in post-anesthesia care unit (PACU), extubation time, recovery time, PACU stay time, discharge time were recorded. RESULTS: Compared with group R, the incidence of EA was significantly lower (38.0% vs. 18.0%, P = 0.005), the maximum PAED score during recovery was significantly lower (7.7 ±3.3 vs. 8.9 ± 3.4, P = 0.027), and the Ramsay sedation score was significantly higher at 15 min after admission of PACU (4.4 ± 1.1 vs. 3.8 ± 1.4, P = 0.01), as well as discharge of PACU (2.0 ± 0.3 vs. 1.8 ±0.4, P = 0.03) in RF group . There was no significant difference in extubation time, recovery time, PACU stay time, discharge time, pain score (discharge of PACU and 2 h after operation) between two groups (P > 0.05). CONCLUSION: A single-dose injection of fentanyl (1 μg/kg) during anesthesia induction can increase the degree of sedation and reduce the incidence of EA in PACU after pediatric daytime adenotonsillectomy.

Objective:To discuss the clinical efficacy of laparoscopic radical cystectomy in the treatment of bladder cancer after partial cystectomy.Methods:The clinical data of 30 patients who underwent laparoscopic radical cystectomy after PC in Sichuan Provincial People's Hospital from March 2016 to August 2020 were retrospectively analyzed. Including 24 males and 6 females with an average age was 62.5 (45.5-82.5)years.6 out of 30 cases underwent pelvic lymph node dissection during PC. All patients had definite pathological diagnosis for the high-grade urothelial carcinoma after PC, and the tumor staging was pT 2-3bN 0M 0.5 patients received postoperative adjuvant chemotherapy with gemcitabine and cisplatin, 6 received postoperative adjuvant radiotherapy, 13 received postoperative adjuvant radiotherapy and chemotherapy, and all patients were received maintenance intravesical instillation. Median time for local tumor recurrence after PC was 9(5-29) months, all patients had pathological diagnosis for the high-grade papillary urothelial carcinoma, cT 2-4N 0M 0 stage.The average tumor diameter was 3.5(2.5-4.5)cm, an average number of tumors was 2(1-3). Laparoscopic salvage cystectomy was performed after recurrence.General anesthesia, supine position, 5 ports were inserted through the abdominal approach. Standard pelvic lymph node dissection (PLND) was used to clean the pelvic lymph nodes. Those who had underwent PLND no longer clean the obturator and peripheral iliac vessels, but including the common iliac vessel and the bifurcation of the abdominal aorta and lymphatic tissues around the inferior vena cava, as well as the presacral lymph nodes. Results:All 30surgeries were successfully performed. The average operative time was 270(240-310)min, average estimated intraoperative blood loss was 180(50-300)ml, and there was no blood transfusion during the perioperative period.The average number of lymph nodes dissected was 18 (10-27). There were 4 cases with positive lymph nodes, of which 3 cases were positive for 2 obturator lymph nodes, and 1 case was positive for 3 obturator and external iliac lymph nodes. No serious intraoperative complications occurred.No lymphatic leakage occurred. The average drainage duration was 4(3-7) d, and postoperative hospital stays was 9(7-20)d. The postoperative pathology was invasive high-grade papillary urothelial carcinoma, and pathological TNM stage was pT 2-4aN 0-2M 0.13 patients received postoperative adjuvant chemotherapy. The average postoperative follow-up time was 23(3-31) months. There were 2 cases of pelvic recurrence and 1 case of retroperitoneal lymph node metastasis. These 3 cases received adjuvant chemotherapy and radiotherapy. Conclusions:Radical cystectomy should be the primary treatment for recurrence of bladder cancer after partial cystectomy.

Objective:To investigate the predictive value of cerebroplacental ratio (CPR) for adverse perinatal outcomes of induction of labor in prolonged pregnancy.Methods:This retrospective study recruited 315 singleton pregnant women who had induced labor due to prolonged pregnancy (≥41 gestational weeks) in the First Affiliated Hospital of Chongqing Medical University from January 1, 2019 to April 30, 2020. Based on the occurrence of adverse perinatal outcomes (emergency delivery due to persistent abnormal fetal heart rate monitoring, umbilical artery blood pH at birth <7.2, 5 min Apgar scores<7, transferring to neonatal intensive care unit after birth, chorioamnionitis and vaginal delivery converted to cesarean section), they were divided into two groups: case group ( n=76) and normal group ( n=239). Clinical features and umbilical artery blood flow, middle cerebral artery (MCA) flow and CPR measured in the last ultrasound scan before induction were compared between the two groups using student's t-test, Mann-Whitney U test and Chi-square test. Receiver operating characteristic (ROC) curve was used to analyze the predictive values of umbilical artery blood flow, MCA flow and CPR for the adverse perinatal outcomes. Multivariate logistic regression analysis was used to screen the meaningful predictors. Results:Compared with the normal group, the umbilical artery pulsatility index (PI) (0.9±0.1 vs 0.8±0.1, t=-5.458, P<0.001) and the percentage of abnormal CPR (<1.0) increased significantly [21.1%(16/76) vs 6.3%(15/239), χ2=14.190, P<0.001] in the case group, while the MCA-PI and CPR decreased significantly (1.1±0.2 vs 1.3±0.3, t=5.658, P<0.001; 1.2±0.3 vs 1.6±0.5, t=8.940, P<0.001). The areas under the ROC curves of umbilical artery PI, MCA-PI and CPR for predicting adverse perinatal outcomes were 0.71, 0.71 and 0.77, respectively. CPR had the highest sensitivity (0.74) compared with umbilical artery PI (0.68) and MCA-PI (0.71), but the specificity of them were similar (0.67, 0.66 and 0.66). Multivariate logistic regression analysis showed that only CPR was the independent risk factor for adverse perinatal outcomes ( OR=0.028, 95% CI: 0.010-0.080, P<0.001). Conclusions:As an indicator for early prediction of adverse perinatal outcomes of induction of labor in prolonged pregnancy, CPR was more sensitive but less specific.
